High Voltage Laboratory (HVL)

The High Voltage Laboratory at the Milan Vidmar Electric Power Research Institute (HVL) is the leading testing institution in high voltage technology in Slovenia. As the testing laboratory it has the ISO-EN 17025 international accreditation for high voltage testing. The laboratory's activity is intended for research, development and education as well as testing for the needs of regular operation of important electrical power facilities.

With its capacities, the laboratory ensures testing according to the highest standards in various testing conditions, from normal conditions to tests in simulated rain conditions.

Highly qualified and specialised staff manage the modern measuring and testing equipment as well as carry out laboratory measurements, supported by scientific and research departments. This results in ensuring top quality analytical processing and appropriate interpretation of results of measurements and tests.

Two mobile units are operating within the scope of the High Voltage Laboratory and they are intended for routine tests of electrical machinery and devices at installation sites. Both units are functionally equipped and intended for diagnostic measurements of individual groups of electrical machinery and devices.

With regard to the laboratory's capacities and the use of individual sets of standard and non-standard measuring and testing methods, the laboratory enables a comprehensive scientific and technical consideration of the issues related to high voltage electrical technology. From the applicative aspect, the laboratory ensures quality diagnostic consideration of electrical devices in various fields for the needs of preventive maintenance, the assessments of envisaged life span and the establishment of operational reliability:
